Research interests + projects

Our group focuses on using high-fidelity numerical simulations and analytical tools to understand the physics behind the hydrodynamics and thermodynamics of particle-laden flows for different applications in renewable energy, sustainability and fibrous materials. Examples of these applications are:

– Microplastics in natural environments: Accumulation of non-biodegradable plastic in marine environments has created serious threats to the aquatic ecosystems and the well-being of human beings. We focus on processes, such as fragmentation, aggregation, and slender body interactions with turbulence, that determine the fate of microplastics in the oceans.

– Fiber suspensions: Flexible fibers suspended in a fluid are widely used in the manufacturing process of  biomaterials and hydrogels. We examine the assembly of flexible fibers and fiber/fluid interactions in fiber suspensions.

– Solid Particle Solar Receivers (SPSR): In SPSRs, a mixture of gas and solid particles receives concentrated solar radiation. The technology of SPSRs is rapidly evolving globally. To optimize the thermal energy that can be extracted from the mixture, we focus on gaining a better insight into the heat transfer between the radiated particles and the background flow.
